HW, I agree. I've not heard of them before and they are located on hollowed grounds. I was told that historically, that this site produced great wines and that it is returning to form. I'm always sketptical about these things. Al la Calon Segur, Nicolas-Alexandre, marquis de Ségur (1695–1755) was a Bordeaux wine maker who during his lifetime was known as the "Prince of Vines" due to his ownership of Château Lafite, Château Latour, Château Mouton and Château Calon-Ségur, but it was Segur that owned his heart. I love Calon Segur too but it does not mean that it makes better wine than Lafite, Latour or Mouton.... only that I can afford it.
